The ECL118S subwoofer features easy-to-use controls. Reverse polarity, use the lowpass filter to set a crossover frequency and adjust the power amp’s master output level. Designed to complement any full-range PA loudspeaker, and a perfect companion for the ECL series, the ECL118S active subwoofer delivers a powerful, clear, and accurate low-end punch. With its 18-inch low-frequency transducer, driven by 2400 watts (peak) of a hybrid Class D power, it provides plenty of detailed bottom end. Despite its power, the ECL118S is portable, compact, and lightweight, with a rugged, tour-grade enclosure. It’s easy to transport and suitable for mobile applications, as well as installs, with integrated provisions for the included caster kit, and ergonomic handles on both sides.
